I'm sending my data via WeatherLink directly to the NWS in San Diego. They provided me with the WeatherLink template and acknowledge that they are still trying to find a solution to the hourly rain issue (right now the rain rate is sent to them). I upload hourly and they would like to see the total rain for the past hour only.

One solution I mentioned to them was if I switched to VWS (^vxv122^) or WD (%hourrn%). But I have yet to get the OK from them. So I was looking for a solution in WeatherLink.

There are undocumented WeatherLink tags? Does anyone have a list of them?

Have you tried contacting Davis? They might have an answer. If they don't have it then maybe point it out to them to put on the "wish list" for there next software release. Seems logical since VWS and WD already have it.
